STMicroelectronics VNB10N07-E

Overview

VNB10N07 from STMicroelectronics is a fully autoprotected monolithic power MOSFET in PowerSO-10 package, integrating linear current limiting (10 A), overvoltage clamp (70 V), thermal shutdown (150 °C), diagnostic feedback via input pin, and direct gate access for analog driving. It replaces standard MOSFETs in DC–50 kHz inductive load switching applications such as automotive body control modules and industrial solenoid drivers.

For engineers reviewing the VNB10N07 datasheet, VNB10N07 pinout, VNB10N07 application, or VNB10N07 equivalent, key selection criteria include its integrated fault detection capability, 0.1 Ω R_DS(on) at 10 V drive, thermal shutdown hysteresis (150 °C trip / 135 °C reset), and compatibility with TTL-level logic inputs without external level shifting.

Technical Context

The VNB10N07 implements ST's VIPower M0 technology to embed protection circuitry directly on-die: a voltage-controlled current limiter sets I_lim = 10 A independent of input voltage, while an internal avalanche-rated clamp limits V_DS to 70 V during inductive turn-off transients. Its input pin serves dual roles-gate control during normal operation and fault-sink path (100 Ω) during thermal shutdown.

Switching behavior is defined by controlled dV/dt and di/dt (60 A/µs turn-on slope), with total input charge Q_i = 30 nC at V_DD = 12 V. The integrated source-drain diode exhibits V_SD = 1.6 V at 5 A and t_rr = 125 ns, enabling fast freewheeling in relay and motor drive topologies.

FAQ

What is the maximum continuous drain current for VNB10N07?

The VNB10N07 features an internally limited linear current of 10 A, enforced regardless of input voltage or temperature. This is not a pulsed rating-it is the absolute maximum sustained current before thermal shutdown activates. Actual usable current depends on PCB copper area and ambient temperature, with 5 A achievable continuously using a 10 cm² 2-oz copper pour per side.

Can VNB10N07 be used as a high-side switch?

Yes-the VNB10N07 is configured as a high-side switch with source tied to ground and load connected between supply and drain. Its input pin controls the internal gate, and the integrated protection functions remain fully active. No external bootstrap circuitry is needed, unlike standard N-channel high-side drivers.

How does fault feedback work on the input pin?

During thermal or overcurrent fault, the internal protection disconnects the input from the gate and connects it to ground through a 100 Ω resistor. Monitoring the input pin voltage reveals a drop to ≤0.5 V, signaling fault condition. This requires no additional components-only a microcontroller ADC or comparator input.

Is external heatsinking required for 5 A operation?

At 5 A and 25 °C ambient, junction temperature rise is ~62.5 °C (R_thj-case = 2.5 °C/W × P_cond ≈ 2.5 × 2.5 W). With a 10 cm² 2-oz copper pour, case-to-ambient resistance is ~30 °C/W, resulting in ~155 °C junction temperature-exceeding safe margin. A small external heatsink or forced airflow is recommended for continuous 5 A operation.
